Happens also on aarch64:
f:
        cmp     w0, 0
        ble     .L2
        cmp     w1, w2
        cset    w7, lt
        cmp     w7, 0
        csel    w0, w0, w1, ne
        ret
        .p2align 3
.L2:
        cmp     w1, w2
        cset    w7, gt
        cmp     w7, 0
        csel    w0, w0, w1, ne
        ret


cset followed by cmp against it and zero.
